Regarding the problem section, I solved about 10 pages worth of grammar questions, but I erased all of them. However, traces of the erasure remain to some extent, so please refrain from purchasing if you are concerned about this. There are no writings on the other problems. Regarding the answer explanation section, I don't think there are any writings. I only solved a little bit in April of my third year of high school, so I think there are almost no writings other than the above, but I apologize if I missed anything. I scribbled on the cover of the problem section, so I filled it in with a blue ballpoint pen. Considering the traces of erasing about 10 pages of writings and the filling in of the cover scribbles, I will sell it at a lower price than other sellers. Also, the class name and name欄 have been cut out.
